Getting Started

Introducing the Heat-N-Glo Gas Appliances

Heat-N-Glo direct vent gas appliances are designed to operate with all combustion air siphoned from outside of the building and all exhaust gases expelled to the outside.

The information contained in this Installers Guide, unless noted otherwise, applies to all models and gas control systems. Gas appliance diagrams, including the dimensions, are shown in this section.

Pre-install Preparation

This gas insert fireplace and its components are tested and safe when installed in accordance with this Installers Guide. Report to your dealer any parts damaged in shipment, particularly the condition of the glass. Do not install any

unit with damaged, incomplete, or substitute parts.

The vent system components and trim surrounds are shipped in separate packages. The gas logs are packaged separately and must be field installed.

Read all of the instructions before starting the installation. Follow these instructions carefully during the installation to ensure maximum safety and benefit. Failure to follow these instructions will void the owner’s warranty and may present a fire hazard.

The Heat-N-Glo Warranty will be voided by, and Heat-N-Glo disclaims any responsibility for, the following actions:

• Installation of any damaged fireplace or vent system component.

• Modification of the fireplace or direct vent system.

• Installation other than as instructed by Heat-N-Glo.

• Improper positioning of the gas logs or the glass door.

• Installation and/or use of any component part not manufactured and approved by Heat-N-Glo, not withstanding any independent testing laboratory or other party approval of such component part or accessory.

ANY SUCH ACTION MAY POSSIBLY CAUSE A FIRE HAZARD.

VENTING AND INSTALLATION

1. Heat -N-Glo gas inserts are designed for recessed in-

stallations into solid fuel Masonry or Factory Built Non Combustible fireplaces that have been installed in accordance with the National, Provincial, State and local building codes.

WARNING: Under no circumstances is cutting

of sheet metal surfaces allowed for installation. If the factory built fireplace has no gas ac-

cess holes provided, an access hole of 1” diameter (25mm) or less may be drilled through the lower sides or bottom of the combustion chamber in a proper workmanship like manner.

3. To assure top performance, safety and efficiency, inserts must be installed with an approved flue liner as per CAN/ CGA B-149 or National Fuel Code ANSI Z223 and these instructions.

WARNING: THE SOLID FUEL FIREPLACE HAS

BEEN CONVERTED FOR USE WITH GAS ONLY AND CANNOT BE USED FOR BURNING WOOD OR SOLID FUELS UNLESS ALL ORIGINAL PARTS HAVE BEEN REPLACED AND THE FIREPLACE HAS BEEN REAPPROVED BY THE AUTHORITY HAVING JURISDICTION.

4. The solid fuel fireplace’s flue damper must be fully locked in the open position or removed for installation.

5. The chimney must be cleaned and in good working order and constructed of noncombustible materials.

6. Make sure that all chimney cleanouts fit properly so air cannot leak into the chimney.

7. Install the insert without the trim surround and make all gas, venting, and electrical connections.

8. Install decorative trim surround. Please refer to instructions included with the trim surround.

Ensure there are no obstructions to side air

passages by the decorative trim once it is installed on insert.

When planning a fireplace insert installation, it’s necessary to determine:

• The vent system configuration to be used.

• Gas supply piping.

• Whether optional accessories—devices such as a wall

switch or remote control—are desired.

2. Minimum fireplace opening requirements are shown in Figure 1 of this installation manual. The firebrick (refractory) can be removed from a factory built fireplace in order to gain minimum gas insert opening requirements.

Installing the Insert

Step 1. Installing the Vent System

Vent System Installation Precautions

Before starting installation of vent kits, the installer should read these instructions and the Vent Kit Instructions to ensure that a proper vent installation is completed.

Consult your local building codes before beginning the installation.

WARNING: THIS GAS INSERT AND VENT AS-

SEMBLY MUST BE VENTED DIRECTL Y TO THE OUTSIDE AND MUST NEVER BE ATTACHED TO A CHIMNEY SERVING A SEPARATE SOLID FUEL BURNING APPLIANCE. EACH GAS APPLIANCE MUST USE A SEP ARATE VENT SYSTEM. COMMON VENT SYSTEMS ARE PROHIBITED.

Vent System Approvals

Model: Vent System CFX-ZC LINK-DV30, LINK- DV4-30

Table 1

Table 1 and Figures 3 through 5 show the vent termination caps and systems approved for use with these models. Approved vent system terminations are labeled for identification. 3-inch diameter listed flexible aluminum and stainless steel gas vent is used for both the incoming combustion air and exhaust vent pipes. NO OTHER VENTING SYSTEMS OR COMPONENTS MAY BE USED. Detailed installation instructions are included with each vent termination kit and should be used in conjunction with this manual.

Horizontal Venting

The vent system on this model CANNOT be terminated horizontally.

Vertical Venting

The vent pipes MUST be connected to the proper collars on the unit AND the exhaust vent pipe MUST be connected to the termination cap or the unit will not operate. The combustion air vent pipe CAN be connected to the termination cap or it can terminate inside the chimney. The bottom opening of the chimney must be sealed around the vent pipes if the combustion air vent is NOT connected to the termination cap. See Figures 3, 4 and 5.

NOTE: The minimum vertical rise (exhaust vent) is 14 feet and the maximum vertical rise is 40 feet. These dimensions are measured from the starting collars of the unit to the end of the last section of vent pipe. See dimension V in Figure 3.

A vertical vent termination system installed on this model will include one (1) length of 3-inch flexible vent pipe for the combustion air, one (1) length of 3-inch flexible vent pipe for the exhaust air, one (1) pipe-to-cap adaptor, and one (1) SLK-991DA or SLK-980D Vertical Termination Cap.

NOTE: The damper of the masonry chimney may need to be removed to allow installation of the flexible-vent pipe.

This fireplace has been altered to accommodate an insert and should be inspected by a qualified person prior to re-use as a conventional fireplace.

NOTE: The above label, located in the instruction package, must be affixed to the existing fireplace prior to installation.

For zero clearance factory built woodburning fireplaces, the use of kit LINK-ZC-ADP in place of the standard square flashing will allow you to mount the adaptor and cap on metal pipe. Additionally, the use of kit FLASH-DAMP will seal off the damper opening when terminating the inlet air vent pipe just above the damper. These 2 kits are recommended for zero clearance, factory built woodburning fireplaces.

Connecting the Vent Pipe

Install the 3” flexible vent pipe(s) down through the chimney. Secure 3” collar to the end of the flexible vent pipe for exhaust using 3 screws. Attach provided 3’ section of stainless steel flexible vent pipe to this collar. Slide the gas insert into place, and position any excess flexible vent pipe back up into the chimney.

NOTE: The 3’ section of stainless steel flexible pipe may be cut to aid installation provided that a minimum of 2’ is maintained.

Using the provided T-handle pull down tool, reach through exhaust opening in exhaust collar by its center pin. Pull down until exhaust collar (or collar attachment bracket) extends through exhaust opening. The collar should slip fit through the molded 3 inch opening. Carefully readjust liners to align if necessary.

Secure in place by sliding retainer pin through the provided holes in the exhaust collar. See Figure 4.

Step 9. Before Lighting the Appliance

4. Attach surround by lifting slightly above front fireplace opening, such that surround hangs on top of the front frame of the unit. The bottom should swing into place such that studs (lower corners of unit) protrude through slotted holes.

5. Secure in place with provided wing nuts.

NOTE: PLACE THE THREE INSULATION PIECES INTO THE CAVITIES AT THE BACK OF THE SURROUND BEFORE POSITIONING THE INSERT INTO THE FACTORYBUILT OR MASONRY FIREPLACE. THIS INSULATION WILL HELP SEAL FOR COLD AIR LEAKS.

Before lighting the appliance, be sure to do the following: Remove all paperwork from underneath the fireplace. Review safety warnings and cautions

• Read the Safety and Warning Information section at the beginning of this Installers Guide.

Double-check for gas leaks

• Before lighting the appliance, double-check the unit for possible gas leaks.

Double-check vent terminations for obstructions.

• Before lighting the appliance, double-check the unit for possible obstructions that could be blocking the vent terminations.

Double-check for faulty components

• Any component that is found to be faulty MUST BE replaced with an approved component. Tampering with the appliance components is DANGEROUS and voids all war- ranties.

A small amount of air will be in the gas supply lines. When first lighting the appliance, it will take a few minutes for the lines to purge themselves of this air. Once the purging is complete, the appliance will light and will operate normally.

Figure 12

Figure 12 shows the minimum vertical and corresponding maximum horizontal dimensions of mantels or other combustible projections above the gas fireplace.

Subsequent lightings of the fireplace will not require this purging of air from the gas supply lines, unless the gas valve has been turned to the OFF position, in which case the air would have to be purged.

NOTE: The fireplace should be run 3 to 4 hours on the initial start-up. Turn it off and let it cool completely. Remove and clean the glass. Replace the glass and run the fireplace for an additional 8 hours. This will help to cure the chemicals used in the paint and logs.

Step 10. Lighting the Appliance

You’ve reviewed all safety warnings, you’ve checked the appliance for gas leaks, you know the vent system is unobstructed, and you’ve checked for faulty components. Now you’re ready to light the appliance.

Maintaining and Servicing Your Appliance

Appliance Maintenance

Although the frequency of servicing and maintenance will depend on use and the type of installation, you should have a qualified service technician perform an appliance checkup at the beginning of each heating season. See the table below for specific guidelines regarding each fireplace maintenance task.

IMPORTANT: TURN OFF THE GAS BEFORE SERVICING YOUR FIREPLACE.

Replacing old ember material Frequency: Once annually, during the checkup. By: Qualified service technician. Task: Brush away loose ember material near the burner.

Replace old ember material with new dime-size and shape pieces of Golden Ember (DE-93) and Glowing Ember (050-

721). New ember material should be placed alternately on top of the burner - a layer of Golden Ember, a layer of Glowing Ember, and so on. Save the remaining ember material and repeat this procedure at your next servicing. For more information, see Placing Ember Material.

Cleaning Burner and Controls Frequency: Once annually. By: Qualified service technician. Task: Brush or vacuum the control compartment, fireplace

logs and burner areas surrounding the logs.

Checking Flame Patterns, Flame Height Frequency: Periodically.

By: Qualified service technician/Home owner. Task: Make a visual check of your fireplace’s flame patterns.

Make sure the flames are steady - not lifting or floating. See Figure 13. The thermopile/thermocouple (standing pilot) tips should be covered with flame. See Figure 6.

MAKE SURE THE FLAMES ARE STEADY—NOT LIFTING OR FLOATING.

Figure 13. Burner Flame Patterns

Checking Vent System Frequency: Before initial use and at least annually

thereafter, more frequently if possible.

By: Qualified service technician/Home owner. Task: Inspect the external vent cap on a regular basis to

ensure that no debris is interfering with the flow of air. Inspect entire vent system for proper function.

Cleaning Glass Door Frequency: After the first 3 to 4 hours of use. As neces-

sary after initial cleaning.

By: Home owner. Task: Remove and clean glass after the first 3 to 4 hours of

use. After the initial cleaning, clean as necessary, particularly after adding new ember (flame colorant) material. Film deposits on the inside of the glass door should be cleaned off using a household glass cleaner. NOTE: DO NOT handle

or attempt to clean the door when it is hot and DO NOT use abrasive cleaners.
